Since photons themselves carry no electric charge, they cannotbe accelerated by electric fields the way that charged particlescan. As a consequence, it is difficult to produce photons with verylarge energies. One idea is to use Compton back-scattered photonsto form a high energy photon beam since the cross-section(probability of occurrence) for this process is large. As anexample imagine a laser with wavelength λ = 300 nm is directed atan oncoming beam of electrons of momentum 500 GeV/c. What is themaximum energy that a final state photon can have in thisscenario?
